WILLIAM B. J UPP, 0F BROOKLYN, NEW YORK, .ASSIGNOR TOINTERNATIONAL MOTOR COMPANY, 0F NEW YORK. N. Y., A `C0RPORA'JIION OF DELAWARE THRoTTLn-CONTROLLING MEANS Fon INTERNAL-COMBUSTION ENGINES' Application filed August 1.9,1927. seriai No. 214,126.

The present invention relates to automatic controlling devices for the throttles of internal combustion engines and applies par ticularly where the engine is used in conjunction with electrical units Jfor service in vehicles operating through an electric drive.

In a service of this character, where the engine is operated completely'through electrical instrumentalities and all manual controls are eliminated, it is extremely desirable to reduce the number of control wires to a minimum to avoid too great a complexity of connections and adjustments as well as make the control cable as small las possible.

In view of the above considerations, an object of the present invention is to provide a throttle control which a'ords a greater number of throttle adjustments than there are control wires by means of mechanical inter connections which are actuated by means of suitable devices which operate individually or collectively at the instance of a current impulse through the appropriate control wires.`

A further object of the invention is to combine a heat and spark control with a throttle control of the above character, thus further eliminating control wires and simplifying the mechanical and electrical construction, in addition to simplifying the operation of the engine.

Further and other objects of the invention will appear as the description proceeds and reference will now be had to the accompanying drawings forming a part hereof for a more detailed description of the invention, wherein:

Figure l is a side elevation of an internall combustion engine upon which the controlling means is carried.

Figure 2 is a plan view looking down upon the housing which carries the control means.

Figure 3 is a diagrammatic illustration showin the successive positions to which the lin f6 is moved upon proper energization of the magnets.

Referring particularly to Figure l, a indicates an internal combustion engine of any desired form carried upon frame Z) and having a throttle connection c, a heater valve d and a spark lever e. i

Upon the frame b is secured a U-shaped housing f having an upwardly extending portion f with spaced parallel walls to carry 'a .rock vshaft f2. Suitable operating means f, suoli as electromagnets, or air valves operatedby electromagnets, are secured to the bridge of the U-shaped bracket f. An arm f4 connects the armatures f5, or otherA means yactuated by f3, and connected to the arm at a point away from the center thereof is a lin/k f6. This link is connected' to a crank arm fwhic'h is securely mounted on rock shaft f2- Upon thev rock shaft f2, are mounted crank arms Vc, ci and e,fthese arms being connected lto their lrespective control meansin the followingmanner. v Alink cis connected to a crank arm "c3 which is mounted upon the .throttle controllshaft of theV throttle c. A similar link cl2 is connected with a'cran'k arm d3 which is carried with the heater valve ci and in this manner the throttley and heater valve are operated simultaneously by the controlling kdevice carried upon the U-shaped bracket A link-e2 is connected to a crank arm e3-which is carried upon a transversely extend-ing rock shaft e4 and a link-e5, connectedfto another crank arm on rock shaft e* extends longitudinally of the engine and operates throughfa linkage e6 and a spark controlling arm e.;"It will be apparent that the spark lever` e is controlled simultaneously with'. .the heatandthrottle valve.

In operation, the link f6 will be moved downwardly through three successive stages, thus affording four positions to which the throttle may be moved. Upon energization of the right hand magnet the link f6 will be moved from the position in which it is shown in the top view of Figure 3 to the position shown inthe second view of Figure 3. Upon deenergization of the right hand magnet and energization of the left hand magnet, the link f6 will be moved from the second position in Figure 3 to the third. Upon energi'zation of both magnets simultaneously, the link f6 will be brought to the position shown in the lowest illustration of Figure 3. The

From the above description it will be seen that this invention combines in a single mechanism the means for controlling, automatically, not only the throttle but also the heater valve and the spark lever. The mechanism is of simple construction and capable of being applied, or removed, With great facility.

Vhat I claim is:

1. In a controlling mechanism for the throttle, heat and spark of an internal combustion engine, a pair of actuating means, a U-shaped bracket secured to the engine structure, means to secure the actuating means to the bridge of the Ufshaped bracket, an arm connected between the actuating means, an extension to the bracket forming opposed sides, means to journal a rock shaft in the sides, a crank on the shaft, means connecting the crank with the arm at a point nearer one of the actuating means than the other, a plurality of operating cranks on the shaft, means connecting the cranks to the throttle, heat and spark controls respectively, and means to effect the actuation of the actuating means in a desired order.

2. In a controlling mechanism, a plurality of actuating means, a floating arm connected to the means, a shaft, means to connect the arm with the shaft at a point nearer one of the actuating means than the other, and means to effect the actuation of the actuating means individually and simultaneously.

A throttle control for operating a throttle in a predetermined number of successive stages comprising a plurality of actu ating means, floating means interconnecting the actuating means, means ,to connect the interconnecting means With the throttle control at a point on the interconnecting means a greater distance from one actuating means than another, and selective electrical means to effect the actuation of the actuating means individually and simultaneously.

This speciication `signed this 17th day of August, A. D. 1927.
